Hm... believe it or not, I just learned the command drawfillpolygon today! I messed with it, and here's what I got, try entering 100 to see the effect I mean. Smaller numbers aren't that outstanding
Note: try using numbers like 50, 100 or 200 or 300, but 500 will probably end up crashing ur environment.
recommended over 25 though lol
I think it gives it an almost 3D look, but more like glassy transparent.
